MACHINE FOR USE IN MAKING BOXES.

Application filed September 13, 1919. Serial No. 323,450.

To all whom it may concern:

Be it known that 1, DAVID A. LANDERS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Machines for Use in Making Boxes, of which the following is a specification.

My invention relates to machines for use in making boxes, crates or the like and particularl for use in making wirebound boxes, crates, blanks or parts thereof.

Among other objects, the invention is intended to provide improved mechanism for positioning the staples or fasteners by which the box materials are secured together and the binding wires attached thereto.

The invention will be described by refer ence to an illustrative embodiment shown in the accompanying drawings, in which Fig. 1 is a side elevation'of one end of an approved type of wirebound box-blank machine embodying my invention.

Fig. 2 is -a longitudinal vertical section of 25 the same illustrating a finished box blank being delivered from the machine and as sembled box sections for a succeeding blank to be operated upon.

Fig. 3 is a detail view, in cross section, of one of the work-conveying chains and its supporting guide. 7

Fig. 4 is an enlarged side view of the feed and staple positioning mechanism.

Fig. 5 is an enlarged side view of the staple positioning mechanism showing a correcting device for the same.

A box blank machine consists generally of a gang of binding-wire applying and stapling mechanisms for wiring together box sections on a work support, the two being relatively movable for stapling the wires at intervals depending upon the progression of the'work between successive operations of the staplers.

In the illustrative machine, the staplers and associated mechanisms, one complete unit of which is shown in Fig. 2, are relatively stationary in the side frames 1, and

the work is supported and advanced by a propriately formed to receive the deats of the box sections, said chains running in conveyor 3 comprising link side chains ap-- guides 5 on supporting rails 6 and trained around the driven sprocket wheels 7.

Cleats and superposed sheets of side material composing box sections are assembled on the conveyor chains in proper relation to provide a box blank or blanks, the sec tions of each blank being held in proper position on the chains by spacer blocks 4 attached at intervals dividual chainlinks, As the work progresses beneath the staplers, a plurality of continuous binding wires, drawn from suitable supply reels, not shown, are introduced in proper relation to the box sections to be stapled thereto, the wires being led between the rollers 9 and thence under the rollers 10 at the feet of the stapler bodies, and being pulled along with the work by virtue of their attachment thereto at preceding points. Certain of the wires alined with the box cleats are stapled through the sheets thereto, so as to connect such wires to both the sheets and cleats and secure the latter together; and intermediate wires are or may be stapled to the sheets alone and clinched on their under sides by co-action of the staple drivers with anvils 12 supported on the cross frame member 11.

as shown in Fig. 3.

The illustrated staplers 13 are of the type;

disclosed in the patent to Thompson,

1,258,625, dated March-5, 1918, comprising staple formers and drivers adapted at every operation to cut and form staples from staple stock wire, fed thereto by rollers 14, and to drive the same over the binding wires into the work. Said staplers are mounted on the stationary cross-head 15 and actuated by the vertically reciprocating crosshead 16, working in guides 17 of the side frames 1, and operated by a pitman 18 from i an eccentric 19 on the main shaft 2, there being a similar operating connection at either side of the machine. The feed rollers 14 for the staple stock wire are also operated from the main shaft by an eccentric 20 and a connecting rod 21 working a pawl and ratchet device 22 for rotating the rollers intermittently.

It will be understood that a sta le is formed and driven at every reciprocation of the cross-head 16, the staple being driven on the downward stroke thereof while the maon the side bars of in terial is momentarily at rest, the eirtent bf movement of the material between the successive operations of the staplers determinin the spacing between successive staples.

tep-by-step movement is imparted to the conveyor by a regulable feed mechanism, the movements being automatically controlled for positioning staples in desired relation on the work. As illustrated, the feed mechanism comprises the pawl-driven ratchet wheel 23 secured to one of the sprocket wheels 7 or on the sprocket shaft 8, and the oscillating driving arm or lever 24 connected to the pawl carrying lever 27 by the toggle bars 25 and 26. For the purpose hereinafter described toggle bars 25 and 26 are pivoted respectively to' the driving1 lever 24 and the 1pawl carrying lever 2 an are also pivota y connected together by the pin 32. The pawl carrying lever 27 carries one or more feed pawls 28 pivoted thereto on the pin 29 and preferably spring held toward the ratchet teeth. The driving lever 24.- and the pawl carryin lever 27 are loosely mounted on the sproc ct shaftand are worked to and fro by the connecting rod 30 from eccentric 31 on the main shaft 2. On the working stroke the feed pawl engages and rotates the ratchet wheel advancing the conveyor a corresponding amount. Thus a regular step-by-step movement of the conveyor is provided.

For variably determining or controlling the feed movements, mechanism is provided to break the toggle connection between the driving lever 24 and the pawl carrying lever 27 during a driving movement of the lever thereby terminating the actuation oi the pawl carrying lever 27 and the travel of the conveyor. Said mechanism may comprise a series of controlling members constituting pattern means and herein exemplified as va' riable length pins or stops ll set in a rotating disc 42 and arranged to be successively presented in the path of a reciprocating bar 39 which is operatively connected to and actuated by arm of link 38, the latter connected to lever 33loosely mounted on the sprocket shaft 8. Said lever 33 is attached to-or unitary with another lever 34, which may be termed a positioning lever, and which is provided with a forked end constituting toggle throwout arms 35 and 36.

'lhe'pin 32 connecting the toggle bars 25 and 26 is normally held in the notch between arms 35 and 36 by spring 43 connecting said pin 32 and lever 33, so that normally said toggle bars are held in position to impart motion from the drivin lever 24 to the pawl carrying lever 2'7. lipon the working stroke of the driving lever 24%, the levers 33 and 3d and the link 38 travel therewith, until the bar 39 strikes one of the controlling pins or steps 41. The lever 33 is then arrested and, upon continued movement of the driving arm 24, the pin 32 rides ontwardly on the inclined plane of the toggle throw-out arm 35, thus breaking the toggle connection between the driving ver 24: and the awl-carrying lever 27 and permitting the riving lever 24 to complete its working stroke without imparting further motion to the feed pawl 28. Upon the return or inoperative stroke of the driving lever v24, the pin 32 will returnto its normal position between arms 35 and 36, rte-establishing the toggle connection, and will move the levers 33 and 34 and consequently the bar 39 back to position for the next forward stroke. During this return movement the pawl-carrying lever 27 will also be returned, the pawl 28 clicking idly over the ratchet teeth 7 of the wheel 23. Thus it is clear that the duration of the drivin connection between tog ls bars 25 and 26 etermines the period or uration of the movement of the ratchet wheel and the conveyor, and that the control or breaking of the toggle connection enables regulation of the cessation of relative feed movements of the work.

It will be noted that in the illustrative construction thus described, the driving lever has a constant stroke, while its operative effect is regulated or varied by controlling the connection between the driving lever and the awl carrying lever, said connection being roken at selected times during the working stroke of the drivin lever. In other words, there is provision or lost motion between driving and driven means of the feed mechanism, said lostmotion being variably initiated during the working stroke and terminating its operative eftect, i. e. discontinuing the feed. Among other advantages this construction permits the feed to start at the slowest movement of the actuating eccentric, that is to say at the beginning of the throw of the eccentric, thus avoiding excessive shock.

lhe disc or turret 42 carrying the controlling pins or steps ll is mounted one shaft 37 suitably gonrnaled in the side frames 1. Said disc has series of bores in which the pins are fitted and secured by set-screws 4d. They are adjusted to project from the outer rim of the disc variable distances to correspond with the length of feed steps desired between llasteners. As many pins are thus set in the pin disc as there are fasteners to be driven in one iron blank, so that the position of each lastener in the blank is controlled. Each pin all is presented in succession into the. path of travel oi the reciprocating bar 39, thereby causing the toggle connection to be brolren and discontinuing the further movement of the work untilalter another fastener has been driven into the work. lt is obvious that the length of the projection of a pinll from the outer rim of the disc l2 determines the point of lid stoppage of the bar 39. A long projection, therefore, produces a. short feed step and vice versa.

For successively presenting the pins 41 into the path of the bar 39, the disc 42 (see Figs. 1 and 4) is revolved in a clockwise direction, at appropriate speed, by a continuously operating friction belt 45 connected to a pulley 46 on the main shaft 2.

A spring pressed latch 47 (see Fig. p1votally connected to arm 49 and working in guides 48 suitably secured to the frame of the machine is normally held by its spring 50 in the path of travel of the set screws 44 to arrest the movement of the disc 42 as each pin 41 is presented in. position to stop the bar 39; the belt drive meanwhile slipping. The latch 47 is automatically withdrawn at proper intervals to permit the further movement of the disc 42 to present the next pin 41 to the bar 39.

For causingsaid latch 47 to be automatically withdrawn temporarily at proper intervals to permit the successive presentation of the pins 41, its operating arm 49 which is pivoted at 51 is connected b link 52 to arm 53 pivoted at '54 and carryin at its lower end a trip'finger 55 pivoted to swing. in one direction only, that is to the ring 56 yieldingly holds the trip finger 55 in its normal vertical position in the path of travel of a lug 57 carried by bar 39. As the bar 39 travels to the left from its position in Fig. 2, the lug 57 displaces and passes under the trip 55 without any operative effect upon the latch, and the spring 56 returns the trip finger to its original position. The bar 39 continues its travel to the left until stopped by the pin 41 which is being held in position by the latch 47 acting on the set screw 44. Lpon the return movement of the bar 39 the lug 57 contacts with the trip finger 55 and carries it to the right (see Fig. 2). This movement swings arm 53, link 52 and arm 49 and withdraws latch 47 from its position of contact with set screw 44. Immediately disc 42 resumes its movement, carrying the set screw 44 past latch 47. The lug 57 carried by the bar 39 quickly passes and releases finger 55 permitting latch 47 to snap back into position to engage and hold the next set screw 44. It will be noted that the withdrawal and return of the latch47 is accomplished so quickly that the pins 41 and their set screws 44 may be located on the disc 42 in as close relationship as may be necessary.

It will also be noted that by reason of the relatively high speed. of the disc 42 by its friction drive said pins 41 may be spaced considerable distances apart. In other words,

the relative position of the pins 41 on the.

disc 42 do not necessarily have to be regular or uniform; the feed movements of the con veyor which locate the fasteners in the work being controlled'by the length of said pins and not by the spaces intervening between alternate widths, there being fourteen staples per blank, three on the narrow and four on the wide sections, and the pin-carrying disc is accordingly provided with fourteen pins. More or less pins may be employed depending upon the number of staples desired in a box blank.

For definitely locating staples in a blank, therefore, the operative 'may plot in any suitable way the desired staple positions, for instance, he may conveniently lay off roughly or by eye on a sample blank or the first blank assembled on the machine, the desired stapling Hpoints and measure their distances apart. e may then adjust the set of pins 41 in a correspondin relationship at proportional distances o with the effector proportionally substract ing from the otherwise normal or possible maximum feed steps, and, accordingly, bringing the work successively .to rest at positions correspondin to the plotted positions of the staples. To facilitate the adjustment of the pins, graduations may be provided on the pins, the graduations bein for instance in the same ratio to standard units of lineal measurements as the ratio of the maximum feed stroke to the ste movementsof the conveyor imparted thereby. The rim of the disc 42 provides a defimte index with respect to which adjustments may be made.

After the adjustment of the pattern of controllin pins, the first blank to be stapled may be a justed with reference to the stapling mechanism so that the first feed-step controlled by the first pin or desired point; which may be done by pre liminaryadvancing the conveyor chains with the assembled work to the proper position. Thereafter the succeeding staples of the blank will be automatically positioned properly by the successive step movements corresponding to the lengths of the pins. However, by virtue of an automatic correcting means hereinafter described, such prelim will bring the work to locate the first staple at the proper in the rim of disc 42 is folded into box form. Such spaces are usually of greater length than the length of a maximum feed step so that after the last staple is driven in a blank two feed steps are usually required to bring the following blank to staple receiving position. If the spaces between blanks were at all times uniform, the feed step between blanks could be controlled by the insertion of an additional pin 41 in the disc 42. To insure uniformity of spaces between blanks, however, it is necessary that the conveyor chains 3 be of a length exactly equal to some multiple of the length of one box blank plus the space between blanks, and while the conveyor chains 3 may be lengthened or shortened by adding or removing certain of the links of the chain, nevertheless it is found very difficult and almost impossible in practice to accurately adjust the length of the chains for boxes of different dimensions so that the length of the chains will be an exact multiple of the length of one blank plus the length of the spaces between blanks. It is desirable. therefore, to provide a correcting or adjusting mechanism which will automatically control the feed step between blanks, regardless of the uniformity of spaces between blanks, so thatwc the next feed step. which is controlled by the initial pin of the pattern ofpins, will properly locate the first staple of the succeeding blank. Such a mechanism is there fore provided to efi'ect a-relative adjustment between the pattern of pins and the work movement for rectifying inaccuracies due to variations in the lengths of the blanks or the spacing thereof, and to insure accurate positioning of staples upon successive blanks.

The illustrative correcting mechanism (see Fig. 5) comprises an arm 58 having a beveled end 59. Said arm is loosely mounted on the shaft 37 so that its beveled end may be swung downwardly across the path of travel of the bar 39. Said arm is connected to the shoe or weight bar 60 by the links 61 and 62. The shoe or weight bar 60 rides on top of the blank material to press it down and hold it in position on the conveyor chains and is secured to the frame of the machine by retractile spring 63. A latch or detector 64, pivotally connected to the weight bar 60 by the pin 65, rides with the weight bar 60 on top of the blank material until it drops into a space between blanks. When the forward edge of the oncoming blank reaches the latch or detector 64, said latch with the bar 60 is carried along with the work and by its movement to the left in Fig. 5 swings correcting arm 58 downward into the path of travel of the bar 39, until the bar 39 strikes some point on the beveled end 59 of the arm 58 and discontinues the movement of the work. During this operation the pin disc 42 has been held stationary by the latch 47 contacting with a screw 443* which is located on the pin disc 42 between the initial pin and the lastpin of the pattern. The correcting arm 58 is, therefore, in effect an additional controlling member having an automatically adjustable length, to deter mine the feed step between blanks, so that the relation of the work to pattern of pins 41 will be properly adjusted for locating staples in the succeeding box blank. After the bar 39 has been stopped by the beveled end 59 of the correcting arm 58, the latch 47 is withdrawn in the manner above described, permitting the disc 42 to advance the initial pin 41 of the pattern of pins to position to locate the first staple in the next blank. After the operation of the stapling mechanism between box blanks the detector 64 is withdrawn from the gap between the blanks by riding up on the inclined surface 66 of the table 67, and is returned to initial position by the tension of spring 63 which draws the weight bar 60 to the right in Fig. 5. This movement of the weight bar 60 to the right in Fig. 5 also swings arms 58 upward and out of the path of travel of bar 39, where it remains until again moved downward by the action of the forward edge of the next blank on the detector 64:.

Thus the correcting mechanism enables the operator to adjust the pattern mechanism or controlling pins for locating fasteners in one blank, and to use said pattern for succeeding blanks in a continuously operating machine without readjustment, the

relation between the pattern of pins and the work being automatically adjusted after the completion of .each blank for accurate operation on the succeeding blank. \Vhile the correcting mechanism as illustrated is controlled by the passage of the work itself through the machine, it is obvious that the mechanism might be controlled by lugs or blocks on the conveyor chains or by other devices correlated with the movement of the work.

During the operation of the staplers between blanks, the staple wire feed may be thrown out to render said stapling operation ineffective and avoid the driving of unnecessary staples. Such throw-out means is well known in the art and, therefore, not illustrated herein. A suitable skip mechanism is shown for example in copending application of S. F. Bauwens-filed March 22, 1919, Serial No. 284,332.

As the work leaves the stapling mechanism, the finished blanks may be stripped from the conveyor chains onto the inclined table 67, and the wires connecting the blanks may be severed by any approved cutting mechanism properly timed or controlled. Other desirable instrumentalities Ill) of this art, such as a conveyor brake ap plied to the ratchet wheel, and manuallyillustrated as they are not essential to the present invention.

Ubviously the invention is not restricted to any particular structural details or mode of o eration, or to any particular type of wirehound box or blank construction. Furthermore, it is not indispensable that all the features of the invention be used conjointly since they may be used to advantage in various different combinations and subcombinations.
